Think of the cells inside your body. They live and die by the millions every day. They are one with you as a person, but still, each cell is a unique individual, with unique characteristics. The cell gets born, and some tiime later it dies, just like you and me. Now think of the planet, we are like it's cells. We are individuals, but at the same time, we are one, in greater terms. Now extrapolate this to the hole universe. The creator and the creation are ONE. God did not only created the universe, but he himself IS the universe. Nothing in the universe is not GOD. So, we are all one with GOD. Love your brothers and sisters (all creatures on earth), but also love yourself.
